![]() “These people were lying in bed comfortably at night with no warning whatsoever,” former Millennium resident Jernigan said of the Surfside catastrophe. ![]() ‘It was a really wonderful place to live’ The surviving members of the Champlain Towers South condo association issued a statement Friday saying, “We know that answers will take time as part of a comprehensive investigation and we will continue to work with city, state, local, and federal officials in their rescue efforts, and to understand the causes of this tragedy.” The cause of the collapse is still unknown. She said ran toward the sound and witnessed the building’s underground garage collapse. Resident Sara Nir, who was in her ground floor condo at Champlain Towers South with her two children the night of the collapse, said she heard loud knocking sounds followed by a boom. Several engineers have told CNN that video of the collapse suggests the failure began near the structure’s foundation, and a 2018 survey prepared ahead of the building’s mandated 40-year certification cited problems in the pool area and the garage beneath it. Search and rescue teams had worked feverishly to locate missing residents until efforts were temporarily halted Thursday amid structural concerns about parts of the building that remain standing. In Florida, at least 24 people are dead and dozens are unaccounted for after the residential building partially collapsed last Thursday. Surfside collapse may have begun in building’s lower reaches “The building remains safe and is in no danger of collapse.” “The structural upgrade currently underway at the tower is intended to prevent further settlement, and recover some of the building’s tilt, rather than to repair damage or provide strengthening,” Hamburger said in the statement. ![]() ![]() The original foundation was built into deep sand and experts determined that nearby projects and a process known as dewatering had weakened the soil under the sinking tower. The retrofit, announced in October following years of lawsuits, hearings and accusations, will finally anchor the building to the bedrock. The piles will then be tied to the existing foundation, he said. “I can state with confidence that settlements experienced by Millennium Tower have not compromised its stability and safety.”Ī $100 million fix, set to be completed next year, involves the installation of piles into the bedrock of downtown San Francisco beneath the building, according to Millennium spokesman Doug Elmets. Previous efforts to reinforce the foundation of the downtown tower came to a halt last summer, when engineers found the building had sunk an inch in the months since the attempted repairs started.“Millennium Tower was designed to stringent earthquake resistance standards and is a much tougher form of construction than typical buildings in Florida, which are not required to be designed for earthquake resistance,” he added. “Once the voluntary upgrade is complete, further settlement of the building at the northwest corner will be arrested, some rebound will occur, and slight additional settlement of the rest of the main tower will act to reverse the tilting that has occurred and close the gap between the elevator thresholds in the adjacent podium building that connects the main tower and mid-rise together,” Hamburger told the San Francisco Chronicle. He has previously warned that the tower’s elevators and plumbing may no longer work if sinking continues at its current rate.Įngineers are working on a retrofit of the building and plan to install 18 steel piles to bedrock, relieving pressure on the foundation, to stop further tilting and sinking as well as possibly reverse some of the movement. The Millennium Tower uses an underground parking garage housed within the smaller structure.ĭespite the gap, engineers “determined that the building is not at risk due to this movement, or any movement likely to occur before construction completion”, Hamburger said, and the gap is not expected to worsen. “Given the present westward tilt of the building, about 24 inches as measured at the roof, the gap between the two buildings in the east-west direction has widened by about 1 inch,” the project engineer, Ron Hamburger, said in a statement to NBC Bay Area.
